Redmi 5 (rosy) No BL Unlock Global ROM Tested Flash File and Guide (Auth Skip)

Learn the “No BL Unlock” method to install Global ROM on a locked Redmi 5 (rosy). We cover the required flash file, Mi Flash Tool, and EDL mode steps.

Flash Global ROM on Redmi 5 (rosy) Without Unlocking Bootloader

Are you using a Redmi 5 (rosy) with a Chinese ROM and want to switch to the Global ROM? The biggest hurdle is usually the locked bootloader. However, for advanced users and repair technicians, there is a method to flash the Global ROM even if your bootloader is locked. This guide outlines the requirements and the general process using specialized tools.

⚠️ Important Disclaimer: This is an Advanced Procedure

This method is not official and carries significant risks. It is intended for experienced users. Proceeding with these steps can potentially brick your device (make it unusable) or void your warranty. You are responsible for your own actions. This method typically requires bypassing Xiaomi’s authorization (Auth) system.

Requirements: Tools & Files

Before you begin, you must have all the correct software, drivers, and files. Failure to use the correct file for your device model (rosy) will result in a hard brick.

• Redmi 5 (rosy) Global ROM Flash File: You need the specific Fastboot ROM (not the Recovery ROM) designed for EDL flashing.
• Mi Flash Tool: The official Xiaomi flashing tool. A specific “no auth” or modified version might be required if not using a separate bypass tool.
• Auth Skip Tool: This is the most critical part. You cannot flash a locked bootloader device in EDL mode without bypassing the Mi Authorization. Required tools include:
  • UMT Pro (Ultimate Multi Tool)
  • DFT Pro (Dongle Phor Tool)
  • Other professional tools that support Qualcomm Auth Skip.
• PC & USB Cable: A Windows PC and a reliable Micro USB cable.
• Qualcomm Drivers: Your PC must have the correct Qualcomm QDLoader 9008 drivers installed to detect the phone in EDL mode.

General Flashing Process (No BL Unlock)

This process uses EDL Mode (Emergency Download Mode), which is a low-level flashing mode for Qualcomm devices.

1. Backup Your Data: This process will completely erase everything on your phone.
2. Install Drivers: Install the Qualcomm QDLoader 9008 drivers on your PC.
3. Boot into EDL Mode: This is the hardest part. Since the bootloader is locked, you cannot use fastboot commands. You must use the “Test Point” method. This requires opening the back cover of your Redmi 5 and shorting two specific test points on the motherboard while connecting the USB cable.
4. Bypass Auth: Once the device is in EDL Mode (visible in Device Manager as “COM port 9008”), open your auth skip tool (UMT Pro, DFT Pro). Use the tool’s Xiaomi or Qualcomm section to perform the “Auth Bypass” or “Disable Auth” operation.
5. Open Mi Flash Tool: After the auth is bypassed, launch the Mi Flash Tool.
6. Load the ROM: Click “Select” and navigate to the folder where you extracted the Redmi 5 (rosy) Global Fastboot ROM.
7. Refresh and Flash: Click “Refresh” in Mi Flash Tool. You should see your device listed (e.g., COM10). At the bottom, select “clean all”. Do NOT select “clean all and lock.”
8. Click the “Flash” button and wait. The process can take 5-15 minutes.
9. Reboot: Once Mi Flash Tool shows “Success,” you can disconnect the USB cable and hold the power button to reboot your device. The first boot will take a long time.

Conclusion: Global ROM Achieved

If successful, your Redmi 5 (rosy) will now boot into the Global ROM with Google Play Services and multiple languages, all without ever unlocking the bootloader. This method is powerful but depends entirely on having the right professional tools like DFT Pro or UMT Pro to handle the authorization bypass.
